A process is disclosed for applying an audio-visual addressing scheme to locate fragments of audio-visual content. The process comprises a definition sub-process, an encoding sub-process, and a decoding sub-process. The definition sub-process defines a logical model for a class of audio-visual media. The logical model is used in the encoding sub-process for encoding an address for an audio-visual resource fragment belonging to the class of audio-visual media. The logical model is also used for locating the audio-visual resource fragment that is associated with the address.
